Application filed October11,1901. sermiiio. 78.364. (to model.)

Be it known that I, PHILIP FErrEN, a citizen of the United States,residing atOleveland, in the county of Guyahoga and State'of Ohio,

have invented new'and useful Improvements inFat-Separating Machines, ofwhich the following is a specification. l My invention relates toimprovements in fat-separating machines, and pertains to a machine whichis adapted to cut or separate the pure fat from the skin of hogs, all ofwhich 1:. will be fully described hereinafter.

The object of my present invention is'to providea machine, animprovement upon the construction shown in my United States Patent No.653, 137, dated July 3, 1900, for performing the work usually performedby hand in the removing 'offat from the skins of hogs andthe cutting ofthe fat into pieces of suitable sizes and the skins into strips ofsuitable widths.

Fig. 2 is a top plan view of the Fig. 3 is a view from thereverse side from that shown in Figul; Fig. 4is a view on the dottedline 4 4, Fig. 1, looking in the direction indicated by arrow. 5 is alongitudinal sectional view'on the line 5 5 of Fig.. 2 and looking inthe direction indicatedby arrow. Fig. 6 is atransverse sectional view 5,the rolls and gears being omitted. l

- Referring now tothe drawings, lindicates a suitable stationary tablesupported upon a framework 2. Extending upward from opposite sides ofthe framework2 are suitable V castings 3, which castings are providedwith the curved'slots 4for a purpose to be presently explained. aPassing transverse the machine and'suitably journaled in thesupportingframebelow the table it is a driving-shaft 5.

Attached to oneend of this driving-shaft are fast andloose pulleys 6 and7, and attached tothe oppositeend of the driving-shaft and located atthe opposite side of themachine is a driving pinion or gear 8. Anupperfeeding-roll 9 has the ends of its shaft 10 journaled in one end of thecurved slot 4, and an upper delivery-roll 11 has its opposite endsjournaled in the opposite ends of the curved rolls.

slots-4, formed, as before stated, in thecastings 3. Connected to andcarried by the driveshaft 5 is a lower feeding-roll 12, and carried by asuitable shaft 14, journaled below the table, is a lower delivery-roll15. Theupper feeding anddelivery rolls are driven from the drivingpinion8 through the intervention of a gear 16, in mesh with the gear 8, and agear 17, attached to the gear 16, the gear 17 engag ing witha gear 18. pthe gear 18 and engages with the pinions 20,

. which are attached, respectively, to the adjacent e'ndsof the upperfeeding and delivery This arrangement causes the upper feeding anddelivery rolls and the lower feed- A gear 19 is attached to 1 ing rollto rotate in the proper direction for feeding the skin with the fatthereon .to the knife 21 (to be more fully described herein= after,)which serves to separatethe fat from the skin. It will be understoodthat the gears 16, 17, 18, and 19 are simply idler or loose gears,serving merely as means for rotating the feeding and delivery rolls. Thelower delivery-roll15 is driven through the medium of the gear 22, whichisattached to its shaft 14 and in engagement with the aforesaid gear 16.Each slot 40f the casting 3 carries a coilspring 23, and the end of eachspring engages, respectively,the ends of the upper feeding and Ideliveryrollsand serves to hold-their feed ing-surfaces normally incontact with the feeding-surfaces of their coactinglower feeding anddelivery rolls, the said table being provided'with transverse slots forthat purpose, as clearly shown in Fig. 5. For the purpose of cutting theskin with the fat thereon into longitudinal strips before it reaches theseparating-knife 21 I provide upper and lower circular slitters orcutters 24,-

which are suitably connected to and carried by their driving andsupporting shafts 25 and 25. The driving-shaft 25 is driven through themedium' of a train of gearing which I will now explain. Connected to theshaft 14 at the opposite side of-the machine from that shown in Fig. 1and at the side of the machine shown in Fig. 3 is a pinion or gear A l26, which pinion or gear is in meshwith a larger gear27. engagement witha pinion or gear 28, carried by the lower .circular slitter orcuttereshaft This latter gear is in turn in 31, the latter gear beingattached to the uption transverse the machine.

per slitter-shaft 25. Through the means of this arrangement the upperand lower slitters are properly revolved for cutting the skin with thefat thereon into suitable longitudinal strips. For the purpose ofaccommodating the circular slitters the upper and lower feeding anddelivery rolls are provided with peripheral grooves 34, as clearly shownin Fig. 2. For the purpose of enabling the separating-knife 21 to moreeasily and thoroughly remove the fat from the skin I cause the saidknife to reciprocate horizontally in a direc- The means foraccomplishing this consists in supporting the knife upon a suitablebearing (which will be presently explained) and upon which it isreciprocated. The means for reciprocating the knife consists of a pitmanor link 35, having its inner end connected with a depending standard 36,the standard in turn being suitably screwed or'bolted to the adjacentend of the knife 21, as clearly shown in Fig. 6. The opposite end of thelink or pitman 35 is journaled upon a suitable wrist-pin 37, carried bya disk 38, the said disk 38 being connected to a counter-shaft 39,(shown in dotted lines, Fig. 2,) the opposite end of the counter-shaft39 carrying a bevel-gear 40. This bevel-gear 40 in turn meshes with thecorresponding bevel-gear 41, which is attached to the adjacent end of atransversely-arranged shaft 43. This shaft 43 is journaled in the framebelow the table and carries at the end opposite to the bevelgear 41 asuitable gear 44, and this gear 44 is in mesh with a gear 45, attachedto the adjacent end of the aforementioned shaft 14. Through the mediumof this mechanism the knife is given a reciprocating movement, as willbe readily understood, as the skin with the fat thereon is fed thereto.The said reciprocating knife 21 is located in a transverse opening 46,Fig. 5, and rests upon suitable adjustable plates or Washers 4'7, Fig.6, for the purpose of permitting the knife to be adjusted vertically topermit of the machine being regulated to accomplish the very bestpossible results. The adjustment is effected through the medium ofsuitable adjusting-screws 48,which either carry or engage the plates orwashers 47, and the knife is thereby forced upward against suitablevertically-adjustable plates 49, located thereabove. These plates 49 areadj ustably connected with the table or bedplate 1 through the medium ofsuitable adjusting bolts or screws 50. i The bed-plate or table at thispoint is located below the knife, as shown in Fig. 5, and provided withtransverse slots 51, through which guiding-bolts 52 pass, the said boltsbeing screwed into the separating-knife 21, all of which is clearlyshown in Fig. 6. In addition to cutting the skin with the fat thereon inthe longitudinal strips it is desirable to cut the fat (after separationfrom the skin) into suitable blocks or pieces, and this is accomplishedthrough the intervention of a revolving knife 55. This revolving knifeis suitably connected to a shaft 56, which in turn carries at one end(see Fig. 1) a suitable pinion 57, and this pinion in turn meshes withan idler-gear 58, and this idler-gear is in turn in mesh with the gear44. This arrangement gives the knife a rotation in the directionindicated by arrow in Fig. 1, and the proper direction for the cuttingof the separated fat into suitable blocks or pieces. Carried on theshaft 43 is what I term a grabroll 62,which is in engagement with thelower delivery-roll 15 and which serves to grab the skin as it passesbelow the knife 21 and prevents it from buckling and assists indelivering the skin with the fat thereon to the said knife, and the skinis then delivered either upon the floor or in any suitable receptacle.The table 1 is suitably recessed, as shown at 60, to permit therevolution of the knife 55, and located at the front end of this recessportion is a stationary or shearing knife 61, with which the knife 55engages for the purpose of aiding in cutting up the fat, as beforeexplained. Y

In operation the skin with the fat thereon is fed into the right-handend of the machine, Fig. 1, which is termed the receiving end of themachine, and is caught by the roughened upper and lower feeding-rolls 9and 12 and carried to'the upper and lower circular slitters, which cutthe skin with the fat thereon into longitudinal slits. These stripsarethen caught by the upper and lower deliveryrolls 11 and 15 and carriedthereby to the separating-knife. The skin is fed to the machine with thefat uppermost, whereby the skin passes through an opening immediatelybelow the cutting edge of the separatingknife 21 below the machine intoa receptacle upon the floor, while the fat passes around over the top ofthe table and is cut into suitable-sized pieces or blocks through themedium of the revolving knife 55. The cut fat then passes to thedelivery end of the machine and is either forced therefrom by thesucceeding pieces of fat or removed therefrom in any desired manner.-
